Hello, I have Windows 7 Ultimate 64-bit, working a-ok, with up-to-date DirectX and drivers. I've not tweaked ~anything or installed anything suspect regarding this issue. I don't have a second display, nor onboard graphics.

When I run Gpu-Z, everything else is displayed/ticked correctly, except the CUDA box. I've tried the Nvidia driver versions 258.96 and 260.99, but the CUDA box is never ticked.

(Hovering over the OpenCL box says "Supported OpenCL 1.0 CUDA", though, if that means anything.)

This happens with Gpu-Z 0.4.7 and 0.4.8, at least. According to random screenshots I've found, CUDA is ticked on other Win7 64-bit systems with the 260.99 drivers and a GTX 470.

I tried running F@H for a test, but I can't tell whether it's using CUDA or not.

Anyway, would anyone happen to have similar experiences? Is this a Gpu-Z problem, or something more problematic?

Thanks!
